In a recent Div 3 contest, I was able to solve 4 problems in 59 minutes with 3 wrong submissions overall. People who have solved 4 questions in more time than me and with more (>3) wrong submissions, are ranked better than me and have lesser penalty. My rating was calculated on even greater rank than actual. I was very strongly expecting an increase in my rating (which I should) and have got a decrease instead. I don't understand whatever this is. My rank on the standings page is 3642 and my rating is calculated on the rank of 4234. Would appreciate some genuine insights on this.
